Glucose amylase,China price supplier

Glucoamylase was derived from submerged fermentation of selected Aspergillus niger. Its sanitation items adopt standard of WHO and FAO GRAS. It can improve quality of products, increase yields, decrease cost and provide advantage conditions to technical progress of enterprises. The products are widely used in starch syrup, alcohol, fuel ethanol, fermentation industry, textile etc.

PRINCIPLE

Glucoamylase can hydrolysis terminal 1, 4 alpha -D-glucosidic bond from the non-reducing ends of starch and yield glucose. It can also slowly catalyze the hydrolysis of alpha-1, 6-glucosidic bond and covert into maltose and dextrin.
